I want to radius a blade for my stanley no. 5 but I don’t have a grinder. Does anyone have a method to do this?

Belt sander mounted upside down in a bench vice and a lot of care….

Flat bastard file.

Mark the radius, file to the line, then sharpen.

(I’d be surprised if someone doesn’t suggest ‘driveway’)

But seriously.

Both suggestions from Wayne and JayT are ways to get the job done. Good luck, Vance.

All you have to do is rock the blade when sharpening. It’ll get a radius on it. Apply more pressure to one corner, then the other. Alternating between strokes. Takes a little while the first time, but it happens and you won’t overheat the blade. :)

I agree with Charlie. Using one of the cheap sharpening jigs with the small wheel on the bottom, just apply pressure to one side for several strokes and then the other. Try to keep it the same # on each side. You can achieve a nice camber without the risk of overheating the blade.

Good luck,

Tim

I was thinking a radius for using the blade for scrubbing. How much radius are you trying to establish?

IMO, do your initial radiusing using the sandpaper on granite “scary sharp” method, before moving your blade w/jig to your hard stone.

FWIW, I severely damaged a softer stone with the metal wheel of the jig digging a divot in the center of the stone, even though that wheel was rolling on a bearing. Sandpaper is easier to “fix” aka replace, than resurfacing a stone.

Rocking will get you a camber, I too was thinking along the lines of a 8” radius curve for scrubbing…

I would not want to rock out an 8” radius. :)

I want a radius. More like a scrub. I can camber the blade freehand but I wanted a little more for milling boards.

It might help to tell us what tools you do have or have access to. There are lots of ways to do it from freehand with sandpaper to an angle grinder.
